 DESCRIPTION OF THE EMBODIMENTS
FIG. 1 is a partial top view of an electronic device of an embodiment of the invention. Referring to FIG. 1, an electronic device 100 of the present embodiment includes a device body 110, at least one first antenna module 120 (shown as two), at least one second antenna module 130 (shown as two), and at least one electrically conductive structure 140 (shown as two). The first antenna module 120 and the second antenna module 130 are disposed in the device body 110 and are, for example, different types of antenna modules that may include various antenna modules applied to long term evolution (LTE) wireless communication technology and various antenna modules applied to a multiple input multiple output (MIMO) wireless communication system, and the invention is not limited in this regard.
The electronic device 100 of the present embodiment is, for example, a notebook computer, and the device body 110 is, for example, a host of a notebook computer. The electronic device 100 further includes a display 150. The display 150 is pivotally connected to the device body 110 and may be opened or closed relative to the device body 110. In other embodiments, the electronic device 100 may be other types of electronic products, and the invention is not limited in this regard.
FIG. 2 is a partial perspective view of the electronic device of FIG. 1. FIG. 3 is a top view of the electronic device of FIG. 2. Referring to FIG. 2 and FIG. 3, in the present embodiment, the electrically conductive structure 140 is, for example, a metal member and includes a first section 142 and a second section 144. The first section 142 is connected between the first antenna module 120 and the second section 144. The first section 142 is extended along a first direction D1, the second section 144 is extended toward the second antenna module 130 along a second direction D2 not parallel to the first direction D1, and the second section 144 and the second antenna module 130 have a gap G therebetween.
In the present embodiment, the first antenna module 120 and the second antenna module 130 are respectively disposed on supporting structures 120 a and 130 a, respectively. The first section 142 of the electrically conductive structure 140 is overlapped with the supporting structure 120 a and connected to the first antenna module 120, and the second section 144 of the electrically conductive structure 140 is overlapped with the supporting structure 130 a and not connected to the second antenna module 130. The supporting structures 120 a and 130 a may be a portion of the plastic casing of the device body 110, or may be an antenna substrate disposed on the device body 110, and the invention is not limited in this regard. In addition, in the present embodiment, the extending direction (the first direction D1) of the first section 142 of the electrically conductive structure 140 and the extending direction (the second direction D2) of the second section 144 of the electrically conductive structure 140 are, for example, perpendicular to each other. However, the invention is not limited thereto. According to design requirements, the extending direction of the first section 142 and the extending direction of the second section 144 may be inclined to each other.
As described above, the electronic device 100 of the present embodiment is additionally provided with an electrically conductive structure 140 connected to the first antenna module 120. The electrically conductive structure 140 includes the first section 142 and the second section 144 respectively having different extending directions. Therefore, the electrically conductive structure may have suitable extending methods based on the signal transceiving requirements of the first antenna module 120 and the structural design requirements of the device body 110, so as to improve the signal transceiving capability of the first antenna module 120 in accordance with the structural design of the device body 110. Specifically, the electrically conductive structure 140 may be regarded as a portion of the radiating portion of the first antenna module 120, and the total extending length of the first antenna module 120 and the electrically conductive structure 140 may be determined based on the frequency band of the signal to be transmitted and received by the first antenna module 120 to amplify the low frequency band of the first antenna module 120 via the electrically conductive structure 140. The invention does not limit the actual size of the electrically conductive structure 140.
In addition, the second section 144 of the electrically conductive structure 140 is extended toward the second antenna module 130 and the two have the gap G therebetween, so that the first antenna module 120, the second antenna module 130, and the electrically conductive structure 140 may have a centralized configuration without affecting the antenna characteristics of the second antenna module 130. As a result, the configuration space of the electronic device 100 is reduced.
Please refer to FIG. 1. In the present embodiment, the device body 110 has a first side 110 a (shown as two) and a second side 110 b adjacent to each other. The first antenna module 120 is disposed along the first side 110 a of the device body 110, and the second antenna module 130 is disposed along the second side 110 b of the device body 110. The electrically conductive structure 140 is disposed at a corner 110 c (shown as two) of the device body 110 located between the first side 110 a and the second side 110 b. The corner 110 c is located at an end of the device body 110 away from the display 150, for example. In other embodiments, the first antenna module 120 and the second antenna module 130 may be disposed at other suitable positions of the device body 110, and the invention is not limited in this regard.
In the present embodiment, the device body 110 has a missing corner N (shown as two) at the corner 110 c (marked in FIG. 1) between the first side 110 a and the second side 110 b, and a portion of the electrically conductive structure 140 is extended outside the device body 110 and located at the missing corner N to be exposed by the device body 110, so that the first antenna module 120 has better signal transceiving capability via the exposed electrically conductive structure 140. However, the invention is not limited thereto, and description is provided below with reference to a figure.
FIG. 4 is a partial top view of an electronic device of another embodiment of the invention. The difference between an electronic device 100A of FIG. 4 and the electronic device 100 of FIG. 1 is that the device body 110 of the electronic device 100A does not have a missing corner at the corner 110 c thereof, and the electrically conductive structure 140 is located in the device body 110 without being exposed, so that the appearance of the device body 110 at the corner 110 c thereof is more visually continuous.
Based on the above, the electronic device of the invention is additionally provided with an electrically conductive structure connected to the first antenna module. The electrically conductive structure includes a first section and a second section respectively having different extending directions. Therefore, the electrically conductive structure may have suitable extending methods based on the signal transceiving requirements of the first antenna module and the structural design requirements of the device body, so as to improve the signal transceiving capability of the first antenna module in accordance with the structural design of the device body. In addition, the second section of the electrically conductive structure is extended toward the second antenna module and the two have a gap therebetween, so that the first antenna module, the second antenna module, and the electrically conductive structure may have a centralized configuration without affecting the antenna characteristics of the second antenna module. As a result, the configuration space of the electronic device is reduced. Furthermore, the electrically conductive structure may be designed to be exposed to the device body, so that the first antenna module has better signal transceiving capability via the electrically conductive structure. Alternatively, the electrically conductive structure may be designed not to be exposed to the device body, so that the appearance of the device body where the conductive structure is located is more visually continuous.
